Lunch Gokon Tantei ~ Koi to Gurume to Nazotodoki to

Amano Yuika (Yamamoto Mizuki) is rather individualistic and uncomfortable around people. She has great powers of observation and is a mystery hunter who solves all sorts of riddles. The setting where she delves into them is quite unexpectedly matchmaking sessions at lunchtime. These riddles are neither murder cases nor savage crimes, but riddles introduced by the participants at the event that Yuika somehow feels compelled to solve. Despite being socially awkward, Yuika completely changes when it comes to figuring them out and does not hesitate to bombard people with questions and prove them wrong. Her colleague Akutsu Reiko (Triendl Reina) goes with her for the matchmaking sessions and they make a contrasting pair with their different personalities and priorities.
